BEIRUT - Syria is facing international calls for tougher sanctions as anti-government protesters vow they will choose death over humiliation at the hands of the regime. The US and Britain called for a tougher stance over Syria's bloody crackdown on protesters on Thursday, demanding tough new international sanctions on President Bashar Assad and his regime. The 5-month-old uprising in Syria shows no sign of slowing down despite a brutal government crackdown that the UN estimates has killed some 2,200 people. Syrians planned to march Friday under the banner “Death Rather Than Humiliation.”
